However, these charts were based on Mitchell’s method using Éléonore’s biggest stope dimensions. They also did not consider any rheology, maximum surface pump pressure capacities or mix density. Using the new system, and its resulting template, backfill personnel can tailor a recipe for each stope to meet the latest sequence and environment conditions. This paper explains how the new paste recipes are selected, as well as the costs savings and productivity increases they enabled. Keywords: cemented paste backfill recipes, rheology, selection template, binder, costs
